Caruso is 4 or 5 years old and weighs about 85 lbs. He is very strong but gets along well with people. However he is very unfriendly to other dogs and should be an only dog in the household. He knows his name and comes when called. Caruso is looking for a very Doberman-savvy owner. He is cropped and docked, and knows how to sit and shake. Did we say he is very strong?
